Okra CAN get very tall. 6 or 7 feet is not uncommon. But it is fairly easy to keep them topped at a comfortable harvesting height. For us, at around 3 ft. tall and when the first okra is about 3 inches long, we begin topping the plant at the main stem about once a week and harvesting the okra as they become ready at 2.5 to 3 inches. You will definitely want/need to wear gloves while trimming. And keep the fruit frozen/crisp until using.

What are your GH temps hitting? Ours will hit 110F at max but Swiss Chard, Tomatoes, and even Kale seem to recover each and every time. We finally pulled our SwCh and Kale after they were 2 yrs old and still producing in favor of fresh plants. They even handled 16F in the GH twice last year. (-20 outside) Froze solid as glass and were fine by mid morning. Nothing else we have grown so far has had such a long run thru so many conditions and we love them both.

I'm in The Bahamas, so heat and excess sun is a big issue here. I have a DWC system. I can grow basil and mint year-round without any problems, they don't mind the heat. I also grow lettuce year-round but whereas I can grow any variety I want in the cooler months, during the summer months I have only found great success with the variety from Johnny's Seeds called "Tropicana", but this is only under some shade sails that block some of the sun so that the lettuce doesn't get cooked in the middle of the day. I' am also trialiing some other heat-tolerant lettuces from Johnny's at the moment, so I'll let you all know which other varieties do well.
